You can try setting a string variable to what door is being used.
SetLocalVarString("CurrentDoor", asEntity);
CreateParticleSystemAtEntity("", "ps_hit_wood.ps", GetLocalVarString("CurrentDoor"), false);
SetLocalVarString("CurrentDoor", asEntity);
CreateParticleSystemAtEntity("", "ps_hit_wood.ps", GetLocalVarString("CurrentDoor"), false);
